Mint Error or Damaged? Decoding the Surface of Not Expensive but Here It Is

Is that a rare lamination flaw, or did someone just scratch it with a screwdriver? Let’s break down how to tell the difference.

I’ve examined thousands of coins over the years. The same hopeful question comes up again and again: “Is this a mint error?” In my experience grading and attributing error coins, the most expensive lesson in numismatics isn’t buying a fake rarity. It’s paying an error premium for post-mint damage — PMD — that happened decades after a coin left the press. The forum thread titled “Not Expensive but Here It Is” is a perfect laboratory for this problem. It’s filled with exactly the coins where collectors get confused: a 1960 cent getting brown on the edges in a PVC binder, 1982 cents stored for 40 years, a blue’ish haze on a coin from an old insert, mint sets with undesirable surface stuff after decades in a box, and shell case copper cents from 1944-1946. None of those surface changes, by themselves, make a mint error. But learning why they are not errors teaches you how to spot the real thing when it matters.

As an error attribution expert, I don’t start by looking at the flaw. I start by looking at what surrounds the flaw. A true planchet flaw was present before striking. It was struck into the coin by the dies. Post-mint damage happened after striking, often long after. The metal tells a different story under magnification. Once you learn to read that story — the direction of metal flow, the sharpness of edges, the color of freshly exposed metal, the way a rim behaves — you stop chasing screwdriver scratches. You start finding genuine laminations and clipped planchets, even on inexpensive coins.

What “Not Expensive” Really Means for Error Collecting

The beauty of that thread is that nobody was pretending their favorites were five-figure rarities. One collector paid $2.00 for a 1960-D small and large date pair and joked he might have overpaid. Another won a coin with a $5.00 raffle ticket. Another bought a circulated piece at auction for $15 in 2009 because he loved honest wear. That is precisely where error attribution matters most. Expensive rarities are usually certified, researched, and fought over by specialists. Inexpensive coins are where you build your eye — and your sense of true numismatic value.

In my experience, the majority of “errors” submitted for opinion on common-date material fall into three buckets:

• Planchet flaws created before striking, such as laminations, planchet cracks, and clipped planchets
• Post-mint damage from tools, jewelry, plating, cleaning, environmental damage, and storage
• Normal minting or storage artifacts like toning, PVC residue, die polish lines, and holder haze that look dramatic in a photo but have no premium

The thread gave us textbook examples of bucket three. A collector tilted a coin to capture a ‘special’ blue’ish haze and assumed it came from the insert. Another noted a 1960 cent getting brown on the edges in a PVC page. Another opened mint sets and proof sets after decades and found “undesirable stuff on the surface” and PAT text where a holder cracked. Those are not planchet flaws. They are chemistry and storage. But to a new collector, a flaky, peeling, brown, or hazy patch can look exactly like a lamination. That is why we need a system.

“Do you have anything that is not expensive but want to say – here it is? Now may be the time.” — The opening challenge of the thread, and the best invitation to learn attribution on coins you can afford to study.

Lamination Errors: The Flake That Was Born in the Strip

A lamination error is one of the most misunderstood genuine planchet flaws. It is not a scratch. It is not peeling toning. It is a separation of the metal itself. It was created when the coin strip used to make planchets had an internal flaw — often a gas bubble, an inclusion, or a weak bond between layers of metal as it was rolled.

How Laminations Form at the Mint

Coin planchets begin as a long strip of metal rolled to exact thickness. If that strip contains a lamination — a thin, horizontal weakness inside the metal — the planchet punched from it carries that weakness into the press. When the dies strike, the metal flows under enormous pressure. If the lamination is near the surface, a small flake may break away during striking. Or it may remain as a raised, cracked, or peeling area that was partially struck over. In my experience grading, the key is that the lamination is struck. You will often see design elements, or the ghost of design, continuing into or over the affected area, because the die pressed into it.

What to Look For Under 10x Magnification

I’ve examined genuine laminations on Lincoln cents, Jefferson nickels, and Eisenhower dollars that collectors confused with corrosion. Here is how I separate them:

• Metal flow follows the strike: On a true lamination, the edges of the flake are often rounded or pressed flat by the die. The surface inside the lamination may show die polish or a faint impression of the design.
• Color is consistent: The exposed inner metal is the same alloy as the coin. On a copper cent, it is copper-colored, not bright and silvery like fresh tooling. It may tone over time, but it does not look freshly cut.
• Location is random but structural: Laminations can appear in the field, over devices, or near the rim, but they do not respect a tool’s path. They do not have parallel striations.
• The rim and edge are usually intact: A lamination is a surface separation, not a chunk cut off the edge. If the edge is missing, think clip, not lamination.
• No displaced metal pile-up: PMD from a screwdriver pushes metal up into a burr. A lamination lifts or flakes; it does not plow.

A common trap from the thread is environmental peeling. Coins stored in PVC pages, like the 1982 cents one poster worried about, can develop a green or brown film that lifts in flakes. That film sits on top of the design. A lamination is in the coin. Tilt it under light, as the poster did to capture the blue haze. PVC haze and holder toning will shift and look like a film. A lamination will cast a tiny shadow at its edge. The design will be interrupted by the missing metal. That eye appeal in a photo can be deceiving. The metal underneath tells the truth.

Clipped Planchets: When the Press Missed the Blank Entirely

If laminations are internal weaknesses, clipped planchets are external absences. A clipped planchet occurs when the strip of metal fed into the press is not perfectly aligned. Or when a previously punched planchet leaves a crescent-shaped void in the strip. The next planchet punched from that spot is missing a segment. When struck, the coin is missing that segment, and the design is incomplete.

True Clip vs. Post-Mint Cut

I’ve seen more fake clips than real ones on inexpensive material. Often created by someone with a file, a saw, or a belt sander. A true clip has a very specific anatomy:

1. The missing segment is a smooth arc: The curve of the clip matches the curve of a planchet blank. It is not straight, not jagged, and not V-shaped.
2. The edge of the clip is struck: This is the critical test. On a genuine clipped planchet, the interior edge where metal is missing shows a raised rim, often called a “Blakesley effect” on earlier types, because the die pressed metal outward into the void. The design is pushed toward that edge and stops with a rim.
3. Devices are truncated by the rim, not sliced: Letters or stars cut by a clip will be incomplete but will end at the raised clip rim. On PMD, a cut slices cleanly through devices and leaves a sharp, unstruck edge.
4. Weight is light, but proportionally: A 5% clip on a cent should weigh roughly 5% light. I always weigh suspect clips. A filed coin often loses weight unevenly and the edge looks polished.
5. The clip edge has mint luster or toning consistent with the coin: Freshly filed metal is bright. A clip that has lived in a collection for 40 years, like many pieces in that thread, will tone with the rest of the coin.

Post-mint damage that mimics a clip usually fails the rim test. Run a fingernail across the missing area. Feel a sharp, knife-like edge with no raised border? You are almost certainly looking at damage. If the coin was cut after minting, the design on the cut edge will be sheared, not pressed. In my experience grading, that single distinction saves collectors from paying $20 to $50 for a $2 damaged coin.

Post-Mint Damage and Tooling Marks: The Screwdriver Test

PMD is the great equalizer. It happens in pockets, in jewelry boxes, in PVC binders, in a kid’s sandbox, and on a workbench. The thread is full of innocent PMD-adjacent stories: coins in 3-ring binders, coins in small plastic sets that became scratchy and foggy, a holder with a crack that made a coin loose, yellowed screws on proof set holders after a few decades. Those holders did not create mint errors. They created surface trauma.

Tooling Marks Tell on Themselves

When I examine a coin for tooling, I look for four signatures that no mint process creates:

• Parallel striations: A screwdriver, file, or rotary tool leaves straight, parallel lines. Mint dies do not scratch in straight lines across devices.
• Displaced metal: Tools push metal. Look for raised burrs, piles, or a shiny trough where metal was gouged. Laminations flake; tools plow.
• Fresh color: Freshly exposed copper is bright orange-pink. Freshly exposed clad is bright silver. If the “error” is brighter than the surrounding fields, it is recent damage.
• Crossing devices unnaturally: A tool mark will cut across letters, rims, and fields without regard to design. A planchet flaw was there before the design was struck, so the design will be affected by it, not sliced by it.

Another form of PMD in the thread was plating and gilding. Posters showed gold-plated Bicentennial half dollars, a 23-karat gold stamp, and a Franklin Mint Jimmy Carter inaugural bronze medal with a Peace Dollar for size. Gold plating is post-mint by definition. It adds a layer after striking. It may be attractive, it may be collectible as a novelty, but it is not a mint error and it destroys original surfaces. The same applies to lacquering, whizzing, and aggressive cleaning. In my experience, collectors who learn to love honest wear — like the $15 circulated coin a poster bought in 2009 because he loved the look — are far less likely to mistake cleaning lines for die cracks or planchet cracks.

Storage Damage Is Not a Planchet Flaw

The blue’ish haze, the brown edges on the 1960 cent, the “undesirable stuff” in mint sets — these are classic storage reactions. PVC plasticizers migrate and react with copper and silver, creating green, brown, or hazy films. Old cardboard holders, sulfur in paper envelopes, and trapped moisture create toning that can look three-dimensional, as one poster noted about a 25th anniversary piece that had never left its velvet box. That patina, however interesting, is not a lamination. A lamination is missing metal. Toning is discolored metal still present under the color.

Actionable takeaway: If you can gently wipe or if the color sits on top of mint luster and shifts when you tilt the coin, suspect storage. If metal is missing and the design is interrupted in a struck fashion, suspect a planchet flaw. When in doubt, do not clean it. Cleaning turns a $5 storage piece into a $1 problem. It turns a genuine lamination into an ungradeable mess.

Case Studies From “Not Expensive but Here It Is”

The 1960 Small Date and Large Date: Brown Edges Are Not an Error

One of the most instructive posts showed a 1960 cent getting brown on the edges, stored in a PVC binder of mostly foreign coins. The poster liked the look. That brown edge toning is almost certainly from the holder, not the mint. The 1960 Philadelphia cent is famous for its Small Date and Large Date varieties — a true rare variety, not a planchet flaw. The poster later paid $2.00 for a 1960-D small and large date pair. The lesson: variety attribution is about die hubbing and date size, which is measured and photographed. Edge toning is about storage. Confusing the two leads to overpaying for damaged coins and underappreciating genuine varieties.

The 1982 Cents in PVC: Forty Years of Risk

Another poster was warned to get 1982 cents out of PVC immediately. He replied that the holder did not have the typical bad smell, was firm like a Saflip, and had been in there for maybe 40 years, so he left them alone. As an appraiser, I understand the temptation. If it survived 40 years, why risk handling? The answer is that PVC damage is cumulative and often invisible until it pits. The 1982 cents, with their composition change that year from copper to copper-plated zinc, are especially vulnerable to spotting and corrosion once the plating is compromised. A hazy, spotted 1982 cent is not a lamination error. It is a storage casualty. Moving it to an inert holder, as the forum advised, preserves what value it has.

Moon Money Tokens and the Blue Haze: Pedigree vs. Surface

The thread’s most valuable detour involved Apollo 11 Moon Money tokens — the copper Green Cheese Penny, Gremlin Dime, and Moon Buggy Penny, plus a silver example. One sold for $1,125 with a Neil Armstrong pedigree, one of 25 presented directly to Armstrong. Without the pedigree, a set of four sold for $300, and a 1969 RD graded example sold for $63. A poster tilted a coin to capture a blue’ish haze and assumed it was from the insert. That haze is exactly the kind of surface film that can be mistaken for a planchet flaw on a token. But on Moon Money, value comes from provenance, composition, and grade — MS68 RD, MS67 RD — not from a surface spot. A genuine lamination on a token would be struck and would interrupt the design. A holder haze sits on top and can often be seen as a rainbow shift. Learning that difference protects you from paying token money for holder damage.

Shell Case Copper 1944-1946: Composition Is Not a Flaw

A poster researched shell case copper cents, noting that for 1944, 1945, and 1946 the cent composition was 95% copper and 5% zinc, using metal recovered from spent World War II shell cases, versus 95% copper and 5% tin and zinc before and after. The Red Book notes the color was a little different, but few people saw the difference. This is a perfect example of a legitimate minting story that is not a planchet flaw. The metal source changed, but every planchet was normal. A slightly different color is not a lamination. In my experience, collectors sometimes see a patchy color on a 1944 cent and call it a lamination or a broadstrike. It is neither. It is alloy and toning. Attribution requires knowing the historical context, not just looking at a spot.

My Attribution Checklist Before You Pay an Error Premium

When a dealer or an online listing offers you a lamination or a clip on an inexpensive coin, run through this checklist I’ve used for decades:

1. Photograph it tilted: Does the flaw cast a shadow like missing metal, or does it shine like a film on top?
2. Check the rim: For a clip, is there a raised, struck rim on the missing edge? For a lamination, is the edge of the flake pressed?
3. Follow the design: Does the design flow into the flaw and get interrupted by striking, or does a tool slice through the design?
4. Look for tool signatures: Parallel lines, burrs, bright fresh metal, or a file pattern mean PMD.
5. Weigh it: Clips should be proportionally light. Laminations are usually only slightly light. A coin that is dramatically light may be damaged or corroded.
6. Check the holder history: PVC, old cardboard, and cracked holders, like the ones described in the thread, explain toning and haze. Ask how it was stored.
7. Compare to known examples: Look up certified examples of laminations and clips for that series. Genuine errors repeat in character. PMD is unique and messy.

If a coin fails two or more of these tests, walk away, no matter how dramatic the photo looks. The most expensive word in error collecting is “maybe.”

What This Means for Buyers and Sellers

For buyers, the thread proves you can build a fascinating error education set for under $100. Buy a genuine, certified lamination on a common cent. Buy a genuine clip on a nickel. Buy a damaged coin with clear tooling marks for a dollar and study it. That contrast, side by side, will teach your eye faster than any book. In my experience grading, collectors who do this stop sending in PMD for certification and start finding real errors in rolls and albums. It also protects your collectibility budget — you pay for history, not haze.

For sellers, honesty about PMD builds trust. Describe storage, holder type, and any tooling. Photograph the coin tilted, not just straight on. A seller who says “lamination-like flake, appears struck, not cleaned” and shows the rim will sell more coins than one who shouts “RARE ERROR” on every PVC spot. The $2.00 1960-D pair, the $5 raffle win, the $15 circulated auction coin — those sellers and buyers were happy because expectations were honest. Coins in true mint condition demand that kind of clarity.

• Buyers: Pay for struck metal, not for stories. Demand rim evidence on clips and metal-flow evidence on laminations.
• Sellers: Disclose holder history. A coin from a 40-year PVC binder needs a warning, not a premium.
• Both: Never clean a suspect error to “see it better.” Cleaning destroys the very evidence that proves it is genuine.

Conclusion: Collectibility Is in the Metal, Not the Haze

The “Not Expensive but Here It Is” thread endures because it captures why people collect. A grandmother’s bank replicas, a Vietnam veteran’s MPC fractionals, a Zimbabwe 10 trillion note that sparked jokes about paying off the national debt, a Naval-themed piece dated to a special year, a Peace Dollar next to a Franklin Mint medal for scale — these are not expensive, but they are special. Error coins belong in that same spirit. A genuine lamination or clipped planchet on a common date is not expensive, but it is special because it was born at the mint, in the moment the press struck, and it survived every holder, binder, and box since.

Post-mint damage, by contrast, is a story of after the mint. A screwdriver scratch, a PVC burn, a blue haze from an insert, a brown edge from a binder — those stories are human, but they are not mint-made. As an error attribution expert, my job is to help you tell those stories apart. Learn the rim test for clips. Learn the metal-flow test for laminations. Learn to recognize tooling marks and storage films for what they are. Do that, and the next time you tilt a coin and see a flake, you will know whether to reach for your wallet or for a safer holder.

That knowledge is worth far more than any single “not expensive” coin in a binder. It is the difference between collecting surfaces and collecting history.
